Two vulnerabilities have been discovered in the PSCP and PSFTP clients, which can be triggered by the SFTP server itself. These issues are caused by the improper handling of the FXP_READDIR response, along with other string fields.

Impact=====

An attacker can setup a malicious SFTP server that would send these malformed responses to a client, potentially allowing the execution of arbitrary code on their system.
